WASHING AND WRINGING MACHINE.

Application filed March 1, 1924. Serial No. 696,318.

This invention relates to laundry apparatus, and more particularly to acombined clothes washing and wringing machine, for household use.

Among the objects of the invention are; to provide a washing machinehaving inn proved means for producing etfective. agitation of the waterand clothes, and to provide two compartments in which clothes ofdifferent grades or kinds may be simultaneously washed; to provide meansin the nature of a press, built into the'machine, and in which theclothes may be placed and subjected to pressure to squeeze the waterout' of them; to provide improved means for causing circulation of thewater from one part. of the washingmachiue to anotheri and to providemeans whereby, whe.u desired, the continued operation of the machine maybe caused to discharge the water therefrom and force it to a higherlevel, as, for example, through a llOfP, into a sink.

\Vith the above and other objects in view. and to generally improve theefiiciency and simplify the contraction of such apparatus, my inventionconsists in the arrangen'ient and combination of parts hereinafterdescrihed and claimed. and illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of the complete machine, parts beingbroken away;

Figure 2 is a vertical, central section therethrough, subitantially onthe line 2-2 of Figure 1;

Figure 3 is a horizontal section on the line 3 3 of Figure 2;

Figure 4 is a side elevation of the lower part of the supportingpedestal and brace, this view being taken in a plane at right angles tothat. of Figure 1, and parts being broken away; I

Figure 5 is a fragmentary transverse section through part of thereversing mechanism shown in Figures 1, 3 and 4;

Figure (3 is a horizontal section on the line 6() of Figure 2;

Figure 7 is a horizontal section substantially on the line 7-7 of Figure9, taken through the top or cover of my improved press cylinder andshowing the locking nzeaus therefor;

Figure 8 is a plan view of such top or cover; and V Figure 9 is avertical section on the line J 9 of Figure 8.

Referring to the drawings in detail, my

improved combined washing and wringing machine comprises a suitable base1, preferably circular in shape, as shown in Figure 3, and supported onsuitable rollers or casters 2. Extending upwardly from the base is arelatively large hollow column or pedestal 3, the base and pedestalbeing preferably t'ormed integral, as by casting. At the top of theiedestal 3 is a horizontal plate or table 4, winch extendspartially-over the interior of the pedestal, as indicated at 4".

Asecoud plate 5, of similar size and shape, overlies the plate 4, andcarries, at its center, a vertically extending cylinder 6, which passesthrough the plate 4 and is disposed centrally of the column or pedestal3.

'lhe clothes container comprises a suitable tub or receptacle 8,preferably formed of sheet metal and cylindrical in shape, the bottompart of such tub or receptacle being interposed between the two plates 4and 5, as shown in Figure 2, and clamped in posi tion by means of aseries of bolts 7. It will be noted that the 'sheet metal preferablyextends between the plates 4 and 5, approximately-up to the cylinder 6so that the bolts 7 pass through the same. From the above, it will beobvious that the cylinder 6, plates 4 and 5, and tub 8, are all unitedwith the pedestal 3, to form a fixed, rigid structure.

Also, carried by the plate 5 and extendingupwardly therefrom, centrallyof the tub or receptacle 8, is another and larger cylinder l2, providedwith numbers of perforations 13, distributed throughout the wallsthereof from the top to the bottom. The top of the cylinder 12terminates slightly below the upper edge of the tub 8, and the upper.end of the tub or receptacle is closed by means of a lid or cover 9.also preferably formed of sheet metal, and provided with a flange whichfits into the upper end of the tub in a well known manner, the upperedge of the tub being preferably beaded, as indicated at S. A pair ofp0ckets or depressions 10, having bars 11 extending across the same. areprovided in the cover 9. to constitute handles, by means of which thecover may be removed. It will be noted that this cover extends entirelyacross the top of cylinder l2. and conceals the same. so that suchcylinder is com pletely housed within the tub or receptacle 8. The t\'lil'ltlcl' 12. which must necessarily be of strong construction, ispreferably formed of cast metal, and is rovided with a rigid closure atits upper en such closure being shown in detail in Figures 7, 8 and 9.eferring to these figures, as well as to Figure 2, it will be seen thatthe closure comprises a circular dish-shaped member 14, having anupstanding flange 14" provided at its outer edge with a radiallyextending flange 14", which is adapted to seat upon the top of thecylinder. Enclosed within the member 14 and rotatably mounted upon acentral screw 16, set therein, is a disk 15, the upper surface of whichis preferably. flush with the upper edge of the flange 14, as shown inFigure 9. By means of cooperating bosses, formed on the member 1a anddisk 15, these members are spaced apart, as shown in Figure 9, and inthis space are mounted a plurality of latches 17, best shown in Figure7.. Each of these latches is pivotally mounted eccentrically of themember 14 upon a screw 18, and the outer end of each latch is adapted toproject, when in one position, through openings 14, formed in the flange1 1. This is indicated by dotted lines in Figure 7. \Vhen, however, thelatches are swung to full line position, they are completely housedwithin the contour of the member 1-1. In order to swing thelatches fromfull line to dotted line position, or vice versa, each is provided witha slot 19, in which works a pin 20, projecting downwardly from the lowerface of the disk 15. Thus, when said disk is oscillated, the latcheswill be shifted, as is obvious. \Vith the latches in the full lineposition, the cover or closure is placed in the mouth, or upper end ofthe cylinder, as shown in Figure 2, and then, whenrthe disk 15 is moved,so as to shift the latches to the position indicated in dotted lines inFigure 7, these latches are caused to project from the periphery of theclosure and to engage in slots formed in the walls of the cylinder 12,thus firmly and rigidly locking the closure to the cylinder.

As clearly shown in Figures 2 and G, the cylinder 12 centrally mountedwithin the tub 8, forms an annular space or washing chamber, in whichthe clothes are contained. In order to efi'ectively wash the clothes,this chamber is provided with suitable rubbing elements, theconstruction of which forms an important part of my invention. Inner andouter rubbing elements are provided, each comprising a series ofvertically extending parallel wooden rods or bars, preferably circularin cross section. The outer series of bars is designated at 21 andconstitutes a lining for the walls of the tub 8, while the inner seriesof bars is designated at 22, and constitutes a lining around the wallsof the cylinder 12. The bars of each series are held together by beingstrung or threaded upon wire hoops 23. Furthernoted that the bars 22 ofthe inner series are spaced apart, at points opposite the perforations13, in the wall of the cylinder 12, so as to permit jets of water,issuing from these perforations, to pass freely between them.

The real or fixed bottom of the tub 8 consists of the plate 5, andassociated parts, but above and spaced from this bottom is a false,movable bottom, consisting of an annular plate 2 which surrounds thecylinder 12. This'plafe 24 is preferably perforated, as indicated at 25in Figure 6, and is rigidly secured by means of screws 26, to an annulargear 26, mounted on ball bearings 26" (see Figure 2). Carried'by theplate 24:, and projecting upwardly therefrom into the annular space,between the cylinder 12 and walls of the tub 8, are two or more brackets01' plates 27, preferably perforated, as shown, and designed to engageand move the mass of clothes.

\Vorking within the cylinder 12 is a piston 28, preferably having arubber cushion or face 29, secured to the upper side thereof. Thispiston is carried by a hollow piston rod or plunger 30, which, in turn,carries at its lower end a second and smaller piston 31, which workssnugly within the cylinder 6. A vertical screw shaft 32 is mountedcentrally within the cylinder (3, and engages a threaded opening in thepiston 31, so that. as said screw shaft revolves, the piston 31,together with the plunger 30 and piston 28. is caused to move upwardlyor downwardly, depending upon the direction of rotation of the screwshaft. In order to prevent the pistons and plunger from rotating withthe screw shaft, a spline in the nature ofa rod 33 is provided withinthe cylinder 12. such spline engaging a notch 34 in the piston 28.

The lower end of the screw shaft 32 is rigidly secured to a clutch disk35, and the disk and shaft are supported by means of thrust bearings 38.resting upon a compression spring 36, enclosed within a housing 37,secured to the base 1. The shaft is also journaled on ball bearings 39,mounted in the lower end of the cylinder 6. and above these bearings isa stuffing box 40, to prevent leakage of water. This stuliing box ispreferably in the nature of a closed chamber having a small pipe 41,extending therefrom through the wall of the pedestal 3. as shown inFigure 3. Suitable plastic material is forced under pressure throughthis pipe and into the stuffing box to fill the same, as indicated inFigure 2,

A second clutch member or friction disk 42, is in contact with andsupported by the til! cated in the space between the lixed clutch member35. the friction disk 42 being secured to the lower face of ahorizontal- 1y disposed bevel gear 423. loosely journaled upon the screwshaft 32.

Beveled pinions 4t and 4.3 me h with the. beveled gear -13. atdiametrically opposite points thereof. these pinions being seemed tostub shafts 4t; and 47. respectivclv. joun lulled in the walls of thepedestal and carrying at their outer ends belt pulleys ls and 49,respectively. ()n the end of the shaft. 4?, beyond the pulley 49. issecured a small beveled pinion .31). This meshes with a beveled gear 51.secured to the lower end of a vertical shaft .311. journaled at itsupper end in the plates 4 and 5. and at its lower end in a bracket 53.carried by the pedestal A housing 5 of sheet. metal. is preferablyarranged to cover and enclose the gear 51.

A stuffing box 53. similar to the stufling box it). is provided adjacentthe upper end of the. shaft 52. to p event leakage therearound. suchstutting box being closed by means of a plug 56. The upper end of theshaft 5'2 carries a pinion .34. which i lo and and it movable bottoms ofthe tub or container. which meshes with the annular gear abovedescribed.

Referring now more particularly to Figures 1. 3 and 4. it will be seenthat belts 5T. 58, run over pulleys 48 and 49. respta-tively. Thesebelts also pass around pulleys 5t) and (30. respectively, which pulleyshave rigidly attached thereto clutch members (31 and ('12. respectively.These pulleys and their as sociated clutch members are loosely mountedupon a shaft (t3. journaled in bearings (34. carried by a swingingbracket (it). pivotally mounted as at (36. on the base of the machine.and having formed integral there with. an upwardly extending bracket(37. through which passes a set screw GS. adapted to bear against theside of the pedestal It is obvious that by tightening this set screw.the bracket (35 may be swung on its pivot. and the tension of the bellsST and 55 thus adjusted.

ltigidly secured to the shaft (33. is a third pulley it). around whichpasses a belt To. This belt also engages a pulley mounted on the shaftof a motor 71. such as an electric motor. supported on a bracket 72.pivoted at one side to a boss carried by the pedestal 25. as indicatedat. Tit in Figure l. liy virtue of this pivotal mounting. the weight ofthe motor Tl serve to maintain the necessary tension on the belt Tl).

Splined upon the shaft hi). at a point between the clutch disks til and(5; is a sleeve 74. somewhat shorter than the distance be tween theclutch disks ()1 and (12. and carrying at its ends complemei'itaryclutch members T5 and To. The sleeve 71 is capable of eudwise movementon the shaft (53,

and when in one position, as illustrated in Figure 3. the clutch memberT5. at one end thereof. engages the clutch disk or member tit. and whenin its oppt;-site po ition. the clutch member it engages the clut h diskor member (32. The reciprocation of the sleeve it upon the shaft 2). isbrought about by means of the following me hani m. split yoke Ti loo-clencircles tln sleetc it. and i held in a groove between annular ll' llldcrs Th. thereon.

In order to produce ciiculation of the water from one part of the clothecontainer to another. I provide a pipe system oo at. extending from thebott m of the wash chamber to the bottom of the cylinder t. as clearlyshown in higiirt Thi pipe ys tem includes a thrce-way \alic Etl.operated by a handle J2. and fr m thi valve extends a nipple SM. towhich a piece of hose may be attached. During the normal operation ofthe machine. th thr i way valve is so set as to establish communicationbetween the pipes W) and ill. and thus. as the piston Ill reciprocatcsin the cylinder (3. water is drawn into and expelled from such cylinder.thus causing circulation and agitation of the water in the clothescontainer.

The operation of my improved -machinc. as a whole. will now be brieflydescribtal.

The clothes to be washed are placed in the annular space or chamberbetween the tub and cylinder 11 and the container is filled loll till

nearly full of water. The motor Tl. running continuously, drives theshaft (33, and this, through the clutch members T5 and (il. as shown inFigure 3, and the belt :37. im parts rotation to the pulley 4S, and[)illit t. 44, thus turning the. gear -13. This. in turn. drives thepinion l5, and through the a nts 50 and 51, shaft 52 and gears fit and2e, causes the plate or t'alseltottom it to revolve, thus moving themass of clothes around in the annular wash chamber and subjecting themto the action of the rubbing elements. At the same time, the gear 43).acting through the friction clutch members 42 and 35, drives the screwshaft 312 in such a direc tion (say) as will cause the plunger carryingpiston 28 to descend. As this piston dcscends, the water contained inthe cylinder 12, below the. same. is forcibly ejected from theperforations 13, in the form of jet which are discharged radially intothe an nular wash chamber, where they impinge upon and pass into themass ot clothes.

After the plate or false bottom 1.! has turned a predetermined distancein one di rection, the pin 89 will strike the lever ss. thus shiftingthe sleeve or chitcl member 74, to its opposite position. The pulley 3a.belt 57, pulley 58 and pinion it now run idle, and power is transmittedfrom the shaft 63 through clutch members To and a2. pulley (it), belt58,2111tl pulley 5%), to the shaft 92 in the opposite direction, andtllet) to the gear 43 This gear will also he driven in the oppositedirection, due to the tact that the point of driving is diametricallyoppte site to that previously employed. Thus, when the sleeve 74 shifts,the direction of rotation of both the shaft 52 and the screw shaft 32 isreversed, whereupon the plate it begins its rotation in tile oppositedirection, and the piston 28 begins to travel upwardly, again forcingthe water out through the perforations 13, in the form of jets. Theratio between the gears 43, 45, so. 5i and 54, and the pitch of thescrew 32 is such that the piston 28 is caused t make a complete strokeduring the time'that the plate it makes a complete oscillation. Thus,the plate and piston operate in unison. It will be observed that theclothes and water in the annular wash chamber are simultaneouslysubjected to agitation in three diti'erent. directions. First, there isthe circune terential movement, due to the rotation of the plate 24.Fecond, there is vertical move ment, due to the surging ot the water upand down in the container, owing to the ttctiOI] ot' the piston 2b, andal o, to the action of piston 31, in the cylinder (3, operating throughthe pipe system Uo hl. 'lhirdly. there is the radial agitation due tothe high pressure jets issuing from the oritices 13 in the cylinder 12,This combined action of circumferential, vertical and Lozzasa siniultanoously. serves to very etiectively and quickly remove all solubl mattert'roni the t'lt)tl!r-. 'lln sluice below bottom or piatc ft. toi'ccci'te :tr tltfjt ihltr oi and, grit or oth r foreign material withwhich the tlothe might have been ctaitaminated, as tretpiently occur intl u e ot' bathing Mitts, etc.

It is sometimes t'ottnd thzi: in the annular wash chamht-r. c rcribed.is :-'o violent as to damag the thinn r tititl tin-er ari cleot'clothing. and in order to avoid this, such tltilt'tiit' articles may beeltertiwly washed by separating them trom the rou; h clothc-- andplacing them in the cylinder 13. Then, it the piston 21 r sciprot:ll(.they are subjected to an intermittent pressing or stpieezim action.which thoroughly tort-es the water through them, and etl'ectivelycleanses them without any rub billg' action. l lcg'mtl iii r provision(ti :1 separate com airtment t'or delicate articles or" clothing, andthe washing oi' such articles without subjecting them to rubbing action,a an important feature of the invention.

in addition to using the cylinder 12 as a scpaiatc wushi compartm nt, 1also contemplate employing it as a press to wring or extra t the surpluswater from the mass of clothes. a'l ter they have been \\'a hed. incarrying out this phase of the operation, the machine is preferablyfittlppt'tl by opening the motor circuit. w th the piston 2h at thelower end ot rokc, uch piston then constituting the tiottoin ot thecylinder l2. The cover or clo ure it is removed, and the mass of clothesis pla ed in the cylinder. The cover or closure it is then replaced andlocked in position, and the llltlellllitf again started. ..\s the j iftil tiaiels upwardly, it compresses the mass ot' clo hes between itselfand the cover or clo ur thus ellectively forcing or squeezing the waterfrom them. The 't unction ot' the triction clutch 3.1- .2 is to limitthe pressure which may be exerted in this way by the piston "R, and thuspre vent damage to the t toiho t r to the machine. Alter a predctcrminctj.ittttt* has been exerted, the clutch member 4:1, carried by the gear43, will sltip, relative to the clutch member 3.3, and the screw hattwill remain stationary.

In many washing machines now on the. market, great ditlicuity isexperienced in removing the water from the machine, after the washing iscomoletcd. it being necessary. in most case to draw the water oti' inbuckets or the like. 'lhi' is due to the fact that. washing nuichine.--as usually built, are lower than the average sink, and therefore. thereis no way to drain the water out of them into such sink. In my improvedma chine, l overcome this detect by means of the cylinder 6 and piston251, above deradial agitation, all operatirn tiaagitation at tit't' thlib J lltt llo

till

scribed. After thc washing is completed. I permit the machine tocontinue to run while throwing the handle 92 over to such a posh tion asto di connect pipes 90 and 9t. and connect pipe at with the nipple all.to whi h a hose leading up to the sink. or other con venient drain, hasbeen connected. \Y th the valve in srch position. it obvious that as thepiston 31 descends. it will force the water in the cylinder (3 outthrough the pipe SH and nipple 93 and hose conne tion. and when thepiston again riseto its uppermost position. as shown in Figure 2. waterwill again till the cylinder t3. enter ng the same through the openingsti". at the bottom of the cylinder 12. Thus. by throwing the threewayvalve into the position described. the piston 31 and cylinder t' arecaused to operate as a pump to discharge the water from the machine andforce it out to a higher level. Thus. the same elements which constitutecirculating and agitating means during the washing operation. may becaused to constitute a pump to force the water out of the machine afterthe waste ing operation is completed.
